Command invocation library to help with Docker builds.

This module primarily exposes utility functions to glue together Docker-based scripts for (e.g.) continuous integration systems like the ocaml-ci. The interface is fairly domain-specific and does not expose all the functionality of the underlying tools. Feel free to contribute more functions if you need them.

type cmd_log = {

command : string;
stdout : string;
success : bool;
status : [ `Signaled of int | `Exited of int ];

}
